Hanna, G.D. 1926, p. 454 on Strombus galeatus:
- "Most of these specimens have weathered out as internal casts, but size and shape are so nearly identical with living ones of this abundant Gulf of Calfornia species that they are unhesitatingly classed as the same."
- Localities, p. 438 ff.:
- 738: From two small washs on the west side of the cut made by the stream in which No. 737 is located, at the base of Coyote Mountain, Imperial County, California, west of the road from Coyoe Wells to Carrizo Spring via Coyote Mountain; W.S.W. Kew, W.E. English and J.P. Buwalda, colls. (This locality is in a branch of Alverson Canon, Original Nos. 4 and 55.)
- 680: Alverson Canon, Coyote Mountain, Imperial County, California; from coarse sandy limestone above coral reef.
- 682: From the first narrow, box canon east of Alverson Canon, Coyote Mountain, Imperial County, California.
